As globalisation continues to accelerate our world inwards, bringing us closer together in terms of global mobility and communication, new ways to answer the age-old question of "Who am I?" are emerging. Plurality of identification and a sense of belonging to blended cultures are becoming more common. This book highlights the cultural identity of Adult Third Culture Kids (ATCKs) to explore a sense of belonging not linked to the boundaries of nations or tied to physical location. As such, it introduces a new concept, that of NatioNILism, or patriotic nation-less-ness, and questions to what extent ATCKs feel a sense of identification with this idea. This will be of particular interest to those who have experienced mobile upbringings and especially useful for Intercultural Competence Training field professionals who are continually seeking new insights into ways in which we understand ourselves and others in communication.
